Metacat

Move the checking if the checksum exists into the create method.

Add the checksum parameter to the method DocumentImple.write.

Add the checksum as a parameter to the method handleInsertOrUpdate.

Add the checksum parameter to the handleInsertorUpdate method.

Add the checksum parameter to the handleInsertAndUpdate method.

Change the signature of the method handleInsertAndUpdate.

Add code to check the check sum by the DigestOutputStream.

Removed the duplicated code to check the checksum in the replicate method since the method D1Node.create, which is called by the replicate method, has the mechanism.

Add some debug information.

Change MetacatHandler.generateOutputName() to use the SystemMetadata.fileName value when it is available. Needs testing.
